1 Motion – Newton’s Laws Gravity – A Closer Look The Universal law of Gravity

2
2 Motion – Newton’s Laws Gravity – A Closer Look The Universal law of Gravity * Gravity is a force of attraction that acts between two massive object

3
3 Motion – Newton’s Laws Gravity – A Closer Look The Universal law of Gravity * Gravity is a force of attraction that acts between two massive object * Two (massive) objects will exert a gravitational attraction with each other no matter how large or small the masses

4
4 Motion – Newton’s Laws Gravity – A Closer Look The Universal law of Gravity * Gravity is a force of attraction that acts between two massive object * Two (massive) objects will exert a gravitational attraction with each other no matter how large or small the masses * Gravity is a fairly weak force unless the masses are quite large

15
15 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? F = G m 1 m 2 / r 2 m1m1 m2m2 r

16
16 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? F = G m 1 m 2 / r 2 m1m1 m2m2 r

17
17 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? F = G m 1 m 2 / r 2 Earth m1m1 m2m2 r r ≈ R earth m 1 = M earth

18
18 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? F = G m 1 m 2 / r 2 = G M earth m 2 / R earth 2

19
19 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? F = G m 1 m 2 / r 2 = G M earth m 2 / R earth 2 This is the force of gravity on m 2 and is, therefore, the weight of m 2.

20
20 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? F = G m 1 m 2 / r 2 = G M earth m 2 / R earth 2 According tot the Second Law: F = G M earth m 2 / R earth 2 = m 2 a

21
21 Motion – Newton’s Laws Gravity – Why does g = 9/8 m/s 2 on the surface of the earth? According to the Second Law: F = G M earth m 2 / R earth 2 = m 2 a Or, at the surface of the earth a = G M earth / R earth 2 = 9.8 m/s 2
